Our Huachen Type-H integrated energy storage PCS and step-up transformer system is a factory-built, pre-commissioned all-in-one solution, designed to store renewable energy from solar and wind sources in battery systems, then invert and deliver stable power to a 3-phase AC step-up transformer on demand. This unit directly solves the core intermittency and volatility challenges of wind and solar generation, ensuring reliable grid integration and flexible power dispatch. The fully integrated system consists of a energy storage power conversion system (PCS), busbar bridge, low-voltage compartment (for communication and power distribution), oil-immersed transformer, high-voltage compartment (with vacuum load switch/circuit breaker), and a heavy-duty enclosure. All assembly, wiring, and testing are completed in our factory, delivered as a ready-to-install package to your project site.
With a compact, space-optimized design, our integrated energy storage inverter and transformer system delivers industry-leading integration density, drastically cutting project land occupation. It eliminates the need for separate equipment rooms and complex on-site assembly, reducing civil construction costs and accelerating project timelines significantly.
The system adopts a premium oil-immersed transformer, offering superior heat dissipation, low noise operation, and excellent cost efficiency. This design ensures long-term stable operation under heavy load, lowering long-term operation and maintenance (O&M) expenses.
The enclosure is treated with a special anti-corrosion and anti-UV process, with excellent resistance to sun exposure, sand and dust erosion. It maintains consistent performance in harsh outdoor environments without additional protective facilities.
The high-voltage side is equipped with a vacuum load switch or circuit breaker, supporting remote control and full-scope system protection. The unit supports unattended operation, further reducing O&M labor costs for your project.
